Method for creating proof image data, proof image data creating apparatus, and computer program product

Abstract

The present invention provides a method of producing proof image data, a proof image data producing apparatus, and a computer program product, and is a technology capable of generating proof image data of a printed matter observed when reproduced using a backing of an arbitrary color, with respect to a printing material having transparency. The disclosed method includes the steps of: (a) acquiring basic proof image data of a color for reproducing a basic printed matter to which a basic backing is applied to a perspective printing material; (b) acquiring texture information of the perspective printing material; (c) acquiring a basic backing color and an observation backing color; (d) producing foreground color proof image data by removing the basic backing color from the basic proof image data; and (e) producing observation proof image data by synthesizing the observation backing color with the foreground color proof image data. Step (e) includes the steps of: (e1) determining an observation color mixing ratio that varies depending on the brightness of the basic proof image data; and (e2) producing the observation proof image data according to the observation color mixing ratio.
